Disclosure to Promote the Right To Information 

Whereas the Parliament of India has set out to provide a practical regime of right to 
information for citizens to secure access to information under the control of public authorities, 
in order to promote transparency and accountability in the working of every public authority, 
and whereas the attached publication of the Bureau of Indian Standards is of particular interest 
to the public, particularly disadvantaged communities and those engaged in the pursuit of 
education and knowledge, the attached public safety standard is made available to promote the 
timely dissemination of this information in an accurate manner to the public.

Occupational Safety and Health and Chemical Hazards Sectional Committee, CHD 8 



FOREWORD 

Ihis Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by 
the Occupational Safety and Health and Chemical Hazards Sectional Committee had been approved by the 
Chemical Division Council. 

This standard was first published in 1980 to unify widely different Codes of practice hoping that those involved 
in the preparation of new or amended schemes for safety colours and safety signs will base their schemes on the 
provisions of this standard. 

This standard also fulfills the need to standardize a system of providing safety information which does not 
require the use of words. The need arises because of the increase in national and international trade and travel 
and the growth of work forces lacking a common language. Further, this standard would help in education which 
is an essential part of disseminating safety information. It is desirable to standardize these systems as lack of 
standardization may perhaps lead to confusion and even accidents, 

Over the years, throughout the world, Code of practice for safety colours and safety signs have been further 
developed to draw attention rapidly to hazardous situations and objects. This revision is based on International 
Standard IvSO 3864-1 'Safety colours and safety signs -^ Part 1 : Design principles for safety signs on workplaces 
and in public areas'. In the preparation of this standard assistance has also been derived from the following 
International Standards: 

BS : 5378 - Part 1 : 1980 Safety signs and colours — Part 1 : Specification for colour and design 
BS : 5378 - Part 2 : 1980 Safety signs and colours — Part 2 : Specification for colorimetric and 

photometric properties of materials 

The composition of the Committee responsible for the formulation of this standard is given at Annex B. 

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, 
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 
IS 2 : I960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in the 
rounded off value should be the same as that of the specified value in this standard.

SAFETY COLOURS AND SAFETY SIGNS 
CODE OF PRACTICE 

( First Revision ) 



1 SCOPE 

This standard prescribes the safety identification 
colours and design principles for safety signs to be used 
in workplaces and in public areas for the purpose of 
accident prevention, fire protection, health hazard 
information and emergency evacuation. 

This standard is applicable to workplaces, all locations 
and all sectors where safety-related questions may be 
posed. However, it is not applicable to the signalling 
used for guiding rail, road, river, maritime and air 
IralTic and generally speaking, to those sectors subject 
to regulations which may differ, 

2 REFERENCE 

The standard given below contains provisions, which 
through reference in this text, constitute provisions of 
Ihis standard. At the time of publication, the editions 
indicated was valid. All standards are subject to 
revisions and parties to agreement based on this 
standard is encouraged to investigate the possibility 
of applying the most recent editions of the standard 
indicated below: 

IS No. Title 

5 : 2004 Colours for ready mixed paints and 

enamels (fifth revision) 

3 TERMINOLOGY 

For the purpose of this standard, the following terms 
and definitions apply. 

3.1 Coefficient of Retroreflection, R' — Plane retro- 
reflecting surface quotient of the luminous intensity 
(/) of a plane retroreflecting material in the direction 
of observation divided by the product of the 
illuminance (E^) of the retroreflecting surface on a 
plane perpendicular to the direction of the incident light 
and its area (A).

R' = 



E,,A 



3.2 Combined Materials — Materials which combine 
the optical characteristics of photoluminescent and 
retroreflective materials. 

3.3 Critical Detail — Element of a graphical symbol 



without which the graphical symbol cannot be 
understood. 

3.4 Fluorescence — Photoluminesccnce in which the 
emitted optical radiation results from direct transitions 
from the photo-excited energy level to a lower level, 
these transitions taking place generally within 10 ns 
after the excitation. 

3.5 Luminance Contrast — Quotient of the luminance 
of the contrast colour L^ divided by the luminance of 
the safety colour L^ where Lj is greater thanL^- 



K^~ 



A 



3.6 Luminance Factor — Ratio of the luminance of 
the surface element in a given direction to that of a 
perfect reflecting or transmitting diffuser identically 
illuminated. 

3.7 Luminescence — Emission, by atoms, molecules 
or ions in a material of optical radiation which for 
certain wavelengths or regions of the spectrum is in 
excess of the radiation due to thermal emission from 
that material at the same temperature, as a result of 
these particles being excited by energy other than 
thermal agitation. 

3.8 Ordinary Materials — Materials which are 
neither retroreflecting nor luminescent. 

3.9 Retroflecting Materials — Materials which 
reflect radiation in a direction close to the opposite of 
the direction from which it came. 

3.10 Phosphorescence — Photoluminescence delayed 
by storage of energy in an intermediate energy level. 

3.11 Photoluminescence — Luminescence caused by 
absorption of optical radiation. 

3.12 Safety Colour — Colour of special properties 
to which a safety meaning is attributed. 

3.13 Safety Marking — Marking which adopts the 
use of safety colours and/or safety contrast colours to 
convey a safety message or render an object or location 
conspicuous. 

3.14 Safety Sign — Sign which gives a general safety 
message, obtained by a combination of a colour and

Review of Indian Standards 

Amendments are issued to standards as the need arises on the basis of comments. Standards are also 
reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that 
no changes are needed; if the review indicates that changes are needed, it is taken up for revision.
